Teddy bears cause autism

The news that the diagnosis of autism may be brought forward is primarily of importance because it may help identify children who will require specialised support. However, it is also interesting because it breaks the co-incidental temporal association that has been part of the reason the MMR vaccine-autism hypothesis gained traction. Since the behavioural cues for autism can’t be picked up well until after one year of age, parental concern about their child being different and autism diagnoses rose after administration of the MMR vaccine. This had unfortunate consequences for the perception of MMR vaccine’s safety.

The causation in the MMR vaccine debacle was neatly illustrated in an article from Prescriber written by Paula McDonald (a former Consultant in Communicable Disease Control).

Aristotle’s concept of syllogisms, says if certain prepositions are met, something distinct will arise from necessity. However, he also noted false syllogisms (In the UK we have an entire publication devoted to generating them, called the Daily Mail). McDonald’s figure illustrates the usual example of the horse being classified as a cat, along with the example of teddy bears and MMR vaccine causing autism.
